IGA platforms and privilege creep: what IAM teams need to know

TL;DR: Identity governance platforms give organisations a structured way to review, certify, remediate, and report access across the user lifecycle, reducing excessive permissions, orphaned accounts, and audit evidence gaps, according to SecurEnds. The core issue is not access control alone, but whether access remains explainable, reviewable, and removed when it no longer matches business need.

NHIMG editorial — based on content published by SecurEnds: Why an IGA platform matters for access reviews and privilege control

By the numbers:

Questions worth separating out

Q: How should security teams implement access reviews in complex IAM environments?

A: Security teams should define review ownership, review frequency, and decision outcomes before automating anything.

Q: Why do role changes create privilege creep in identity programmes?

A: Role changes often add new access without reliably removing old permissions, so users accumulate entitlements over time.

Q: What breaks when access reviews are done with spreadsheets and email?

A: Spreadsheets and email make it hard to prove who reviewed what, whether a decision was completed, and whether rejected access was actually removed.

Practitioner guidance

  • Standardise certification workflows across all critical applications Require each review to capture the reviewer, decision, business justification, and remediation status in one workflow so access cannot be certified without traceable evidence.
  • Trigger access checks on mover and leaver events Connect HR or directory events to governance workflows so role changes and offboarding create immediate review and revocation tasks for the right owners.
  • Normalise entitlements into business-readable terms Translate technical permission names into application and business labels so reviewers can spot excessive access and segregation of duties conflicts without guessing.

What's in the full article

SecurEnds' full article covers the operational detail this post intentionally leaves for the source:

  • Step-by-step breakdown of access review capabilities and certification workflows for business owners and auditors
  • Detailed discussion of lifecycle governance for joiners, movers, and leavers across enterprise applications
  • Specific remediation and reporting features that help teams close audit gaps and track revoked access to completion
  • Practical guidance on selecting an IGA platform for compliance-heavy environments such as SOX and HIPAA

IGA is becoming the control plane for access accountability, not a back-office reporting tool. Once organisations need to prove why access exists and whether it was removed, they are doing governance, not administration. That shift matters across human IAM, service accounts, and adjacent NHI programmes because the same lifecycle problem appears in different forms. The implication is that access evidence must be designed as part of operations, not assembled after the fact.

A few things that frame the scale:

  • 97% of NHIs carry excessive privileges, increasing unauthorised access and broadening the attack surface, according to Ultimate Guide to NHIs.
  • Only 5.7% of organisations have full visibility into their service accounts, which is why access governance needs inventory quality as well as review discipline.

A question worth separating out:

Q: Who is accountable when access remains active after revocation is requested?

A: Accountability should sit with the application owner or remediation owner named in the workflow, not with the reviewer who flagged the issue. If the process does not assign closure ownership, revoked access can remain active indefinitely. Mature programmes track the issue from decision through removal and exception closure.
